The Essay Worth Up to Three Diploma Points
The IB Extended Essay is a 4,000-word independent research paper written under the supervision of a school mentor and submitted as part of the IB Diploma Programme requirements. Together with the Theory of Knowledge essay, the Extended Essay contributes up to 3 bonus points to the Diploma score. A student who achieves an A grade in both the EE and TOK Essay receives 3 additional points on top of their subject scores — the difference between a 39-point total and a 42-point total, which is significant in competitive university admissions.
Beyond the marks, the Extended Essay is the first genuinely independent research project most IB students have ever completed. It asks you to identify a question, design an investigation, gather and analyse evidence, construct an argument, and communicate your findings in academic prose. These skills — not coincidentally — are exactly the skills that university-level study requires. Students who take the Extended Essay seriously are building capabilities that will serve them throughout their academic and professional lives.
Choosing Your Research Question — The Decision That Determines Everything
The Extended Essay research question is the foundation of the entire project. A well-chosen research question makes the essay possible to write well; a poorly chosen research question makes it almost impossible. The characteristics of a strong research question are specificity (it can be fully addressed within 4,000 words), genuine debatability (there is not an obvious single correct answer), methodological feasibility (the evidence needed to answer it is actually available to you), and disciplinary clarity (it belongs clearly to one IB subject, not ambiguously across multiple).
Students who choose research questions that are too broad — "What is the impact of colonialism on African literature?" — produce essays that scratch the surface of a vast topic and satisfy no depth criterion. Students who choose research questions that are too narrow and straightforwardly factual — "When was the Eiffel Tower built and what were its construction challenges?" — produce essays that are descriptive rather than analytical and do not demonstrate the evaluative thinking the assessment criteria reward.
The research question that works is at the sweet spot: specific enough to be answered in depth within 4,000 words, broad enough to require genuine analysis and argument rather than simple factual reporting. An example of a well-scoped IB Economics Extended Essay research question: "To what extent has the implementation of minimum wage legislation in Germany since 2015 achieved its stated objectives of reducing wage inequality?" This question is specific (Germany, post-2015), genuine (there are competing academic views on minimum wage effects), feasible (data is available), and clearly within the Economics subject.
Almost no student's first research question is their final research question. Plan for two to three iterations. After drafting your initial question, share it with your supervisor and ask: Is this researchable? Is it too broad? Is it too narrow? Is it genuinely debatable or does it have an obvious answer? Is the evidence I need actually accessible to me? The revision process is not a sign of weakness — it is the normal intellectual process of refining a question into something genuinely useful. Students who lock in their first research question without revision produce essays of systematically lower quality than students who refine.
The Writing Process — From Research to Draft to Submission
The Extended Essay is not written in a single session. It is written over a process of approximately six to eight months (from initial research question approval to final submission) that involves multiple distinct phases: exploratory reading to understand the topic broadly, focused research to gather evidence relevant to the specific question, note-taking and analysis of gathered evidence, outlining the argument structure, drafting section by section, revising for clarity and coherence, and final polish.
The Abstract (300 words maximum, written last) summarises the research question, the methodology used, and the conclusion reached. The Introduction (approximately 400 words) contextualises the research question, explains why it is worth investigating, and outlines the structure of the argument. The Body (approximately 2,800 words) presents the evidence and analysis, organised into logical sections each advancing the overall argument. The Conclusion (approximately 400 words) directly answers the research question, acknowledges limitations of the investigation, and suggests implications or questions for further research.
The Assessment Criteria You Must Know
The Extended Essay is assessed against five criteria: Focus and Method (the quality of the research question and the appropriateness of the methodology), Knowledge and Understanding (demonstration of subject-specific knowledge relevant to the question), Critical Thinking (the quality of analysis, evaluation, and argumentation), Presentation (adherence to word count, proper use of citations and bibliography, appropriate academic writing conventions), and Engagement (evidence of authentic intellectual engagement throughout the process, assessed through the Reflections on Planning and Progress Form). Understanding these criteria transforms the Extended Essay from an overwhelming open-ended task into a clearly structured achievement goal.
